Oil prices climbed about 3% to a nine-week high on Friday as supply concerns and technical buying outweighed fears that further interest rate hikes could slow economic growth and reduce demand for oil. Both contracts closed at their highest prices since May. “We’re knocking on the door of a major breakout to the upside. I think you’re seeing some short covering here today … because a lot of people have been betting on the short side, said Phil Flynn, an analyst at Price Futures Group. Also supporting crude prices, the U.S. dollar fell to a two-week low after data showed U.S. job growth was lower than expected but still strong enough to likely lead the U.S. Federal Reserve to resume raising interest rates later this month as it has signaled. WTI traded up $2.06 or 2.9% to close at $73.86. Brent traded up $1.95 or 2.6% to close at $78.47.
